Your question is not clear.
Are you planning to discard existing ILMT and install an entirely new ILMT application after BigFix migration?
Is any information from current ILMT need to be migrated?
@ssakunala - Tagging onto this thread. We were forced to uninstall/reinstall BigFix for a small ILMT implementation, as the version they were running was out of support, and would not upgrade with the 9.5 installer. We successfully installed BigFix 9.5 using the existing masthead.
Now the Data Source definition for BigFix will not connect based on a database validation error:
database is from a different deployment (expected epoch 2020-03-23 17:59:39 UTC, got 2023-04-07 17:22:50 UTC)
Can this be corrected by setting the resynchronize_datasources_once parameter to true?
Was the existing BigFix database reused or was a new database created? If a new database was created then the computer IDs will change and the above procedure should help.
The masthead have nothing to do with the computerID assigned to an agent.
The computerID is a unique number assigned randomnly from the server to an agent at registration time.
To ensure the computerID does not change it is required not only the machine an agent is installed on remains the same, but in addition ensure a set of further restrictions agent side … ( it is clear the database on the server need to be the same )
After a server migration, for the agent installed on the server it is simply impossible the computerID remains the same. For other agents in the deployment, having followed the steps indicated in the documentation, no new computerID should have been generated.
